Problems solved by technology

However, in the process of softening the protective film in the traditional hot-pressing device, the lamp tube in the hot-pressing device is easy to age, which leads to the deviation of the heating temperature of the hot-pressing device, which leads to the failure of the protective film to process a curved surface that meets the requirements, and then Significantly increase the defect rate of the protective film

Embodiment approach 1

[0030] Embodiment 1, the imaging unit 30 images the filament 221 of the lamp tube 22 in a light-emitting state. If the filament 221 in the lamp tube 22 is aging, the staff can directly observe the blackened state of the filament 221 on the imaging part 30 . At this time, the staff can directly replace the filament 221 of the aged lamp tube 22 . If the filament 221 is not aging, the worker does not need to replace the filament 221 of the lamp tube 22 . Therefore, the filament 221 in the luminous state is imaged by the imaging unit 30 to quickly and in real time determine whether the filament 221 is aging, thereby quickly and accurately judging whether the filament 221 of the lamp tube 22 needs to be replaced, so that the heat press device 100 can ensure that the plastic blank 200 can reach the softening temperature in real time, thereby improving the product yield of the prepared product. In addition, compared to imaging the filament 221 in the non-luminous state, the aging o...

Embodiment approach 2

[0031] Embodiment 2, most of the same technical content as Embodiment 1 will not be repeated: the imaging unit 30 performs imaging on the filament 221 in a non-luminous state. If the filament 221 is aged, the worker directly observes on the imaging part 30 that the filament 221 is darker than the standard filament 221 and the filament 221 without aging. At this time, the staff can accurately replace the aged filament 221 . Compared with imaging the lamp tube 22 in the glowing state through the imaging unit 30 , imaging the lamp tube 22 in the non-emitting state through the imaging unit 30 can avoid light damage to human eyes.

[0032] In this embodiment, the imaging unit 30 can be set in various ways:

[0033] Embodiment 1, such as figure 2As shown, the imaging unit 30 includes a first mirror 31 . Optionally, the first reflection mirror 31 is a plane mirror. The carrying part 10 has a carrying surface 11 . The first reflector 31 is fixed on the carrying surface 11 . Opt...

Abstract

The invention discloses a hot-pressing device. The hot-pressing device comprises a bearing part, a heating part and an imaging part. A machining space is formed on one side of the bearing part. The bearing part comprises a fixing region and an imaging region facing the machining space. The fixing region is used for fixing a rubber blank. The heating part comprises a fixed plate and a lamp tube. The fixed plate is located in the machining space. The lamp tube is mounted on the fixed plate. The lamp tube is used for emitting light for softening the plastic blank. The imaging part is located in the imaging region. The imaging part is used for imaging a lamp filament of the lamp tube. The hot-pressing device can reduce the reject ratio of products. The invention further discloses a hot-pressing method.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, in particular to a heat pressing device and a heat pressing method. Background technique [0002] Traditional mobile phone screens often need to be attached with a protective film to protect the mobile phone screen from being scratched by external hard objects. In the process of protective film processing, the protective film needs to be bent to a certain extent first. Traditionally, the surface processing of the protective film is generally carried out by a hot pressing device. However, in the process of softening the protective film in the traditional hot-pressing device, the lamp tube in the hot-pressing device is easy to age, which leads to the deviation of the heating temperature of the hot-pressing device, which leads to the failure of the protective film to process a curved surface that meets the requirements, and then Significantly increase the defect rate of the ...
